Fixed my GDB resulting in X-Windows desktop manager crash for Ubuntu
X64 on trace.

That is good to know, I was using the guide at 
http://wiki.lazarus.freepascal.org/Multithreaded_Application_Tutorial.
Maybe you could update it please?

If you do so, please only mention it is as a tip that apparently might 
help if you have problems. There is no reason why using an external 
debug file should make any difference whatsoever, regardless of 
whether you are debugging a single or multi-threaded program.

Dear FPC-All

Debugging in GTK2-Linux of multithreaded GUI is a pain.
Some notes:
I have debugged with Eclipse C++ .so with LCL application as host, 
Eclipse hangs as well.
and entire X stops responding  (seems like X event loop was blocked).
Switching to Text console and killing host application brings desktop to 
life, but this did not help in debugging :-(

Regards, Anton
